ATTACHMENT FOR SPINNING-MACHINES.

To all whom it may concern:

Be it known that I, PORTER D. GOULD, a citizen of the United States, residing at. Hillsboro, in the county of Hillsboro and State of New Hampshire, have invented a new and useful Attachment for Spinning-Machines, of which the following is a specification.

This invention relates to spinning mules, operators, and machines. As ordinarily constructed they operate in such a manner that when the belt is first shipped to start the machine into operation after doffing the carriage moves back against the frame with a sudden jolt, which results in considerable breakage, especially to the teeth of gears and clutches which are employed. In the course of a year the cost of repairs for the parts broken in this way amounts to a large percentage of the cost of the machine.

The principal objects of this invention are to provide a simple and inexpensive means whereby the carriage on this first motion back toward the frame will be caused to move more slowly so that this breakage will be avoided; and to so construct the apparatus that on the subsequent movements, or when the carriage is brought back automatically, the restricting means will not be brought into operation; also to construct the device in such a manner that it will operate automatically and will not require any particular attention.

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, which illustrate certain forms in which the invention may be carried out, and in which Figure 1 is a front elevation of a portion of a machine of the Davis & Furber type, showing how the invention may be applied to this particular kind of machine. Fig. 2 is a similar view showing the parts in another position. Fig. 3 is a similar view showing the parts in a third position. Fig. 4 is a side elevation of a portion of the mechanism. Fig. 5 is a plan of the shipping slide. Fig. 6 is a plan of the fork for limiting the motion of the shipper. Fig. 7 is a fragmentaryelevation showing a portion of an operator of the Johnson & Bassett type, and illustrating how the invention may be applied thereto, and Fig. 8 is a similar view showing how the invention may be applied to a Davis & Furber machine of a later style.

Referring first to the first six figures, it will Specification of Letters Patent.

be seen that a type of machine is illustrated in which the driving belt 10 is adapted to operate on three pulleys, a loose pulley 11, a fast pulley 12 for drawing in, and a fast pulley 13 for twisting and drawing out. The position of the belt on these pulleys is controlled by the shipper 14, which is pivoted at 15 to a projection 16 on a frame 17, and which is provided with an arm 18 operated bya shipper slide 19. This shipper slide has a cam 20 which operates the shipper and is controlled by a rod 21. It has guiding slots 22 and pins 23 which guide the slide. shipper is also provided with an arm 24 normally held up by a spring 25 connected with a twist slide 26. or the like 27 in which the lever 28 operates, this lever having a curved arm 29 which is operated by a roller 30 011 the carriage 31.

It will be observed that the parts so far described are such as constitute features of one of the types of machine known as the Davis & Furber. It is to be understood, however, that the invention is applicable to substantially all types of spinning machines, and that this type is selected for the purpose of illustration merely. In this type of machine the movement'of the carriage toward the frame in the position shown in dotted lines in Fig. 4, operates the lever 28 and elevates the twist slide 26. This operates the spring 25 and swings the shipper to move the belt from the pulley 12 to the pulley 13. This constitutes the automatic operation of this type of machine after it is once started. In order to start it, the slide 19 is operated by hand to turn the arm 18 and ship the belt from the loose pulley 11 to the tight pulley l2. Ordinarily the belt comes clear over on this tight pulley 12, and the carriage is brought back to the frame so rapidly as to cause the damage which has been mentioned above. In order to prevent this in this invention means is provided for stopping the belt in a position such as that indicated in Fig. 2 so that it will not impart full power to the drawing in pulley- 12. In this form of machine, the following mechanism has been adopted for that purpose. On the frame is mounted a bracket 40. On this bracket is pivotally mounted an arm 41 which has a slot 42 through which a bolt 43 passes so that the arm may swing up and down. On this arm is a fork 44 which has a slot 45 through which the bolt 46 passes to connect with the arm 41 in such a manner that the fork may The This twist slide has a slot be adjusted on the arm, and it will be observed that the arm may be adjusted on the bracket. This fork is so located as to engage the arm 18 of the shipper when it is drawn back to ship the belt from the pulley 11 to the pulley 12, and is so adjusted that it will stop it in substantially the position indicated in Fig. 2, with the belt partly on one pulley and partly on the other, so that full power will not be transmitted to the pulley 12 and the carriage will be brought back with a lower velocity than is the case when the belt. is shipped entirely over on this pulley.

Connected with the upper side of the fork is a wire 17, the upper end of which is supported by an arm 48 which may be adjustably mounted on a stud 49 located on the twist slide. The operation of the device when constructed in this manner is asfollows :-IVhen the shipper slide 19 is operated to swing the shipper and bring the belt on the pulley 12, the twist-slide being down on account of the carriage being part way out, the fork 44 will be in the position shown in Figs. 1 and 2, the motion of the arm 18 will be limited so that it cannot move past the position shown in Fig. 2, and the belt will be brought partly 011 the pulley 12, but will remain also partly on the pulley 11 so that power will be transmitted by the belt to move the carriage back. When the carriage is moved back to the position indicated in dotted lines in Fig. at, the twist slide will be forced up, and the wire 47 will force the swinging arm and the fork up into the posi tion shown in Fig. 3 so as to permit the belt to be shipped over on the pulley 13 to move the carriage so as to twist and draw out the yarn. After this position of the parts has been reached, the shipper moves back and forth automatically between the pulleys 12 and 18, but it does not move on the pulley 11 until the machine is stopped. v

It will be seen that as the belt never reaches the position shown in Fig. 2, during the automatic operation, the arm 18 of the shipper always remains in such inclined position during the automatic operation of the machine that the swinging arm and fork are never allowed to fall down into horizontal position, although the twist slide drops on each operation of the carriage far enough to permit them to swing down if the arm 18 were not in a position to prevent it. 'Consequently during the automatic operation of the machine the attachment which has been described remains inoperative. But as soon as the machine is stopped by the operation of the shipper slide 19 to move the shipper back into the position in Fig. 1, the fork drops down into horizontal position when the twist slide drops, and is ready for performing its function when the machine is again started.

In the form of the invention shown in Fig. 7, a horizontal shipper rod 50 carries a bracket 51 on which is adjustably mounted a swinging arm 52 which is provided with an offset or tooth 53, the swinging arm 52 passing through a slot in the frame 54. The drawing-in cam 55 operates after the machine is once started to move the projection 56 thereon into engagement with the adjustable end 57 of the arm 52 and swing it up so that the projection 58 will on subsequent movements escape the edge of the perforation in the frame and pass through the same.

In the form shown in Fig. 8, a shipper 6O pivoted at 61 and having a spring 62 is provided with an adjustable hunter 63, and a swinging arm 64 which operates with the twist is provided with an adjustable projection 65 thereon. On the first motion of the shipper, the hunter 63 engages the plate 65 which is adjusted to such position as to limit the motion of the shipper in the manner indicated," but on subsequent motions, the swinging arm is moved out of the way of the hunter. Whatever the type of machine, it will be understood, that the same principles are carried out to secure the objects of this invention.

IWhile I have illustrated and described certain forms in which I prefer to embody the invention and illustrated the same as applied to certain types of machines, I am aware that many modifications maybe made therein when applied to the same types, and that the invention canbe carried out in many other ways when applied to other types of machines. Therefore, I do not wish to be limited to the particular forms illustrated and described, but

What I do claim is 1. In a spinning machine, the combination with a loose pulley, a tight pulley, a belt therefor and a shipper, of means for limiting the motion of the shipper when the machine is started, to such a position that the belt in the extreme position to which it may be moved by the shipper will be partly on the loose pulley and partly on the tight pulley.

2. In a spinning machine having a carriage, a frame, a belt, and a loose and a fast pulley, the combination with the shipper, of means for holding the shipper in position to keep the belt partly on the loose pulley and partly on the fast pulley when the belt is shipped to start the machine, and until after the carriage moves back to the frame the first time.

3. In a spinning machine, the combination with a shipper, a loose pulley, a fast pulley and a belt therefor, of means for limiting the motion of the shipper to a position in which the belt is partly on the loose pulley and partly on the fast pulley, and means for moving said limiting means to inoperative position while the machine operates automatically.

4. In a spinning machine, the combination w1th a pivoted shipper, of a swinging arm'mounted on the frame, an ad ustable fork thereon for engaging the shipper and limiting the motion thereof, and means for moving the fork into inoperative position when the machine is operated automatically.

5. An attachment for a spinning machine having a shipper, and a twist slide comprising a bracket mounted on the frame, an arm swingingly mounted on the bracket, a fork adjustably mounted on the arm and adapted to engage the shipper of the machine, and means on the twist slide of the machine for holding the fork in inoperative position when the twist slide is raised.

6. An attachment for spinning machines, comprising a bracket mounted on the frame of the machine, an arm pivotally mounted on the bracket, a fork mounted on the arm, a twist-slide, an arm mounted on the twistslide, and a wire suspended from the arm on the twist-slide and connected with the fork whereby when the twist slide is raised the fork will be raised.

7. In a spinningmachine, the combination of a carriage, a belt, a shipper for said belt, means for controlling the shipper to operate the belt so as to transmit only a part of its power to the carriage on its first back ward motion when the machine is first started, and means for rendering said controlling means inoperative while the movements of the carriage are controlled automatically.

8. In a spinning machine, the combination with a carriage, means for automatically controlling said carriage to reciprocate, and manually controlled means for starting the operation of said carriage, of means for controlling the operation of the carriage on its first backward motion to cause it to move slowly, and means for rendering said controlling means inoperative when said automatic controlling means is in operation.

In testimony whereof I have hereunto set my hand, in the presence oftwo subscribing witnesses.
